MC_StopRegist

Description

This function will turn off registration for the specified axis and disarm the specified fast input The inputs are taken into account at each cycle depending on the system periodicity (for example each millisecond). Under certain circumstances this can be insufficient when more accuracy is needed, or if a quick response is required from the system. To fill the gap, a drive may have some Fast Input connections (generally one or two). When an event happens that triggers a Fast Input (e.g. when a sensor sends a rising edge), the detection of a signal occurs faster (which can be 1000 times more accurate than the system periodicity). Then the timestamp associated with this input can be provided to the IPC to take corrective action.

Arguments

Input

En	Description	Enables execution
	Data type	BOOL
	Range	0, 1
	Unit	N/A
	Default	—
Axis	Description	Axis registration to turn off
	Data type	AXIS_REF
	Range	The range of .AXIS_NUM is [1,256]
	Unit	N/A
	Default	N/A
TriggerInput	Description	Structure specifying the fast input to disarm. The structure elements are: InputID INT 0 = Touch Probe 1 / Capture Engine 0 1 = Touch Probe 2 / Capture Engine 1 Range is [0,1] Direction INT 1 = rising edge A rising edge is the transition of a digital signal from low to high. It is also called positive edge, 2 = falling edge, 3 = NA, 4 = toggle between both, falling edge first, 5 = toggle between both, rising edge first, range = [1,5] TrigID INT Axis number of the fast input. 0 indicates this trigger axis is to be the same as the Axis input. range = [0,256] TrigMode INT (TriggerInput.TrigMode) is not presently supported by this function. The TriggerInput.Mode may be supported in a future software version.
	Data type	TRIGGER_REF
	Range
	Unit
	Default

Outputs

OK	Description	Indicates function executed successfully
	Data type	BOOL

• To use Capture Engine 1 modify the input PDOs that are used and add the Latch The control word is used to activate the drive's latch status machine. The latch control word is processed independently of the EtherCAT bus cycle. The status word is used to return the drive's latch status Position 1 parameter.
